dtourolleandClaude Opus 5 b9891e2c04 Merge master into tablet-selection
Two real conflicts, both from work that landed either side of the same
lines rather than against them.

`lib.rs`: the settings controller was hoisted above the People screen's
wiring, and Android's thumbnail-tier eviction registered itself at the
same point. Independent, so both stay.

`library.rs`: manual collection ordering and burst folding each added a
clause to the same two queries. The scoped range read now carries both —
the folding matters there for one step further on than it does in the
grid, because a collapsed burst is one cell, so an ordinal counted over a
list still holding every frame names a photograph several places away
from the one the user pointed at.

dtourolleandClaude Opus 5 a4b9deaf96 Put the people filter where the filters are
Narrowing the grid to two people at once has worked since people became
a selector term, and it was effectively unreachable. The only control
that could add a second person lived on the People screen, behind
selecting them there, and it appeared only once the grid was already
narrowed to somebody — so "photographs with both of them" needed a
two-screen round trip the user had to guess at.

A filter belongs on the filter bar. A "People" chip there opens a tray of
everyone the library knows; tapping a name adds or removes them, and the
any/all chip beside it — already there, and already the thing nobody
found — now has something to sit next to that explains it. The caption
leads the row so a pair of chips means something before either is
pressed.

The tray is a strip under the bar rather than a popup, the way the
develop column's film picker is: the view scrolls as one, so an inline
strip is taller content and not a second overlay to dismiss. It scrolls
horizontally for the same hard reason the bar above it does — a layout
cannot be narrower than its children's minimums, and forty people would
otherwise set the minimum width of the whole view.

The roster is built on open, not kept in step: indexing and regrouping
change who exists, and a list cached at startup would be stale for
exactly the user who has just been naming people. Named first, then by
how much of them the library holds — the catalog orders by face count
alone, which puts a dozen unnamed strangers ahead of the two people the
user actually cares about.

dtourolleandClaude Opus 5 2403f355d6 Tell a tap on a photograph from a hand going past
A brush across the grid opened whichever photograph was under it. Travel
was already answered — the Flickable claims the pointer and the press is
cancelled — but a contact that neither travels nor lasts reaches a
TouchArea as an ordinary press and release, and it was landing the user
in develop.

So a finger now has to stay down for `TAP_MIN_MS` before letting go
counts as opening anything. That is the floor under a tap where the 450 ms
`HOLD_DELAY_MS` is the ceiling: below is a graze, between is a tap, above
is a hold that starts a selection. One scale, three gestures.

Only a finger is held to it. A mouse click is a discrete decision made by
a button and is routinely over in thirty milliseconds, so `cell-pressed`
now reports whether a finger did it — the same finger-id convention the
pinch arbitration beside it already uses — and the dwell applies to touch
alone.

A graze still *selects* the cell it landed on, because the press already
did that. That is the right failure mode: something visible and
reversible rather than a silent nothing, and rather than develop.

dtourolleandClaude Opus 5 6246a2e346 Merge: group the frames of one moment, and let a burst fold away
FR-CULL-5. Frames join a burst when they are adjacent in time and look
like the frame before them -- both, because time alone groups a whole
ceremony and similarity alone groups a studio setup across two days.
Adjacent pairs only, chained; there is no all-pairs step and there must
never be one.

No selection of any kind. The representative is the earliest frame, a
fact about the clock rather than a judgement about the photograph, and a
newly found burst arrives open, so the pass never takes a row off the
screen.

Verified: fmt, clippy --workspace --all-targets -D warnings, 346
dr-catalog tests, 511 dr-ui tests.

dtourolleandClaude Opus 5 115653a262 Mark a burst in the grid, and let it be folded away
The counterpart to the grouping: where the signatures come from, and how a
group reaches a cell.

Signatures are computed from the 256px thumbnails dr-thumbs already holds --
vastly more resolution than a 9x8 reduction can use -- so a library that has
been browsed, or that has synced somebody else's shards, has already paid for
them and no RAW is decoded for this. The consequence is stated rather than
hidden: an image with no thumbnail gets no signature and never joins a burst.
That is self-correcting, and it is why the pass runs when the thumbnail sweep
finishes rather than on a timer. Nothing happens at import and nothing happens
at query time.

The mark is drawn as a child of the cell's TouchArea, for the same reason the
star strip is: a click on it must not also reach `cell-clicked` and throw the
user into develop, and children are hit-tested before the element they sit in.
It is never hidden on hover the way the stars are -- a collapsed burst stands
in for frames that are not on screen, and something has to say so whether or
not a pointer is nearby.

Folding changes what the grid's *query* returns rather than what its cells
draw, because the grid is a window over an ordered query and the frames a fold
hides are mostly not loaded. So the predicate joins VISIBLE in every query
that lists or counts cells -- the window, the header's count, the run a
shift-click resolves, and the ordinal a scrub lands on -- under the discipline
VISIBLE's own comment sets out: present in four places of five is worse than
absent, because the counts disagree with the cells and neither looks wrong on
its own. There is a test for exactly that.

`the_window_read_walks_the_ordering_index` now includes the burst clause. It
asserts on the query plan while holding its own copy of the query, so left
alone it would have gone on reporting green against a query the grid no longer
runs. If the clause costs `images_grid_order` and puts the sort back, that
fails here rather than becoming jitter someone measures in six months.

The pass keeps its own drain timer in a thread-local instead of taking fields
on the library controller, so everything the feature needs to run lives in one
file and the screen that starts it holds nothing.

dtourolleandClaude Opus 5 5a8327824f Keep an edit under a name, not just on the clipboard
FR-DEV-6 asks for three things — named presets, copy/paste between
images, and batch-apply to a selection. The last two have been here for
a while; this is the first.

The format is the sidecar's, deliberately. A preset *is* the non-default
half of a version, so the lines are the same lines keyed the same way,
which makes the two files diffable against each other and lets someone
debugging an edit paste a block from one into the other. One file rather
than one per preset: a preset per file makes the name a path, and every
name then has to survive a filesystem — a `/` becomes a directory, a
name differing only in case collides on one platform and not another,
and renaming becomes two operations that can half-fail. As a key in a
document it is none of those.

Unknown *parameters* needed no machinery. `Preset` already holds
whatever keys it is given and resolves them against the descriptors only
at apply time, so one written by a newer build survives by being stored.
Only lines that are not `op.param = float` at all are preserved
verbatim, which is the sidecar's version-skew promise made here too.

Applying is the paste path with a different source, so a preset reaches
a selection through the sidecar read-modify-write that was already
there: no graph, no decode, no GPU, forty files or one.

Two smaller decisions worth the record. A library that fails to parse is
held empty in memory and *not* written back over — settings regenerate
themselves and this is work, so a parse failure must not be the moment
it is destroyed. And every save persists immediately and rolls the
in-memory copy back if the write fails, so the sheet never lists a
preset the file does not have.

The grid's "Presets" button is gated on the selection alone, unlike the
"Paste to 40" beside it. That button needs a clipboard armed this
session; the preset list is whatever was saved last month, and hiding it
behind an unrelated action is what makes a feature only its author knows
about.

dtourolleandClaude Opus 5 574107bc39 Let a manual collection be put in the order it is meant to be seen in
`collection_members.position` and `Sort::CollectionPosition` have been in the
catalog since collections were, and nothing above dr-catalog has ever written
or read either: `collections::set_order` had no callers, and the grid ordered
everything by capture time whatever it was scoped to — dr-ui does not construct
a `Query` at all, it has its own `GRID_ORDER` constant. So a manual collection
was a set with an order nobody could see or change.

Three pieces, because it could not be fewer:

`grid_order_for` decides the ordering from the scope, and both readers take it
from there. That is the load-bearing part. An ordinal only names a photograph
relative to an ordering, so the window read and the span read have to agree —
a shift-click resolved through a different ORDER BY than the cells were drawn
with selects a different run than the one on screen, and the user finds out
when the export runs. `read_ids_span` already stated that invariant about
`GRID_ORDER`; this widens it to an ordering that depends on the scope.

Only a single manual collection has one. A set draws its descendants' images
too, and two children's positions are unrelated integers that interleave
arbitrarily; a smart collection has no member rows to carry a position at all.
Both fall back to capture time and refuse the drop rather than pretending.

The drop is on the cell, on whichever half of it the finger landed — the
trailing edge is the only way to name the last place in a collection, since
there is no cell beyond the last one to drop in front of.

`reordered` is pure and the membership is rewritten whole. `set_order` sets the
positions it is given and leaves the rest, so a partial write would interleave
the moved run with rows nobody touched; and it is read unfiltered, so what the
filter is hiding keeps its place relative to what the user can see.

dtourolleandClaude Opus 5 6d25d85f18 Make the range gesture visible, and offer the whole grid at once
Touch has had a range gesture for as long as selection mode has: double-tap the
far end. It is invisible, it is unreliable on a grid that scrolls under the
second tap, and it extends from the anchor *before* the two taps moved it — a
rule subtle enough that the code needs two paragraphs to explain it to itself.
Nobody who was not told about it has ever used it.

"Select to…" is the same operation with state you can see. Press it, the strip
stops reporting and says "Tap the last photograph", and the next cell taken is
the far end. It reaches Rust as shift on `cell-pressed`, so it lands in
`apply_press` as the ctrl+shift it already is, and there is no third selection
policy to keep in step with the other two.

This is deliberately not the sweep gesture. A drag that paints cells can only
reach what is on screen, and the ranges that hurt on a tablet are longer than a
screenful — between the two taps here the user may scroll as far as they like,
and the run is resolved by the catalog rather than by what happened to be
loaded. A sweep is still worth having for short runs; it is not what this
should have rested on.

"Select all" beside it, asked of the catalog for the same reason: a select-all
that quietly meant "the hundred cells that happen to be loaded" is a lie the
user cannot see until the export runs.

The double-tap stays. It is tested, and an accelerator that costs nothing is
worth keeping for whoever has already learnt it.

dtourolleandClaude Opus 5 9ac1447139 Ask for the collection's name where the keyboard can reach it
"New collection from selection" created the collection under a placeholder
name and then opened the rename field in the sidebar tree.

On a tablet the sidebar is not on screen. It is instantiated all the same —
app.slint collapses it to zero width and `visible: false` rather than using an
`if`, because an `if` there is a layout loop Slint panics on — so the rename
field was created, its `init` took focus, and Android raised the on-screen
keyboard over a box nobody could see. Nothing else on the screen is focusable,
so the keyboard had nowhere to go: it stayed, the name could not be typed, and
the collection was already written under the name the user did not want.

Asked in a sheet instead, on the same card as the filing and keywording sheets,
before anything is written. That also fixes what was hiding behind it: an
abandoned rename used to leave a "New collection" in the tree, because the
collection existed before the name did.

`Field` gains `take-focus()` so a sheet whose field is the only thing to do in
it can answer the keyboard for the user — a function rather than a property,
because focus is an event and a bound property would re-take it on every
unrelated re-evaluation.

dtourolle f12aece07e Make storage pluggable, and prove it with a folder backend
`RemoteBackend` existed from the first release and bought nothing it was
designed for. Seven files in `dr-ui` constructed a `NextcloudBackend`
directly, an account *was* a server URL beside a DAV user id, the local
cache directory was named after a hostname, and the launch screen knew
that signing in meant a browser handshake. The trait was real; the seam
was documentation.

A trait over operations is only a quarter of it. Pluggable storage needs
four things, and this adds the other three:

- **Capabilities** — already there, and the reason the engine can drive
  two backends at the speed each actually runs at.
- **Configuration** — `dr_sync::Account`: where a library lives, in
  whatever form its connector addresses, with no server in it. Loads
  every existing config unchanged (`backend` defaults to `nextcloud`,
  `endpoint` is stored under its historical `server` key), and
  `Account::namespace()` reproduces the old catalog directory byte for
  byte, because changing it would abandon a catalog, its thumbnail
  shards, and the sidecars holding unsynced offline work.
- **Registration** — `BackendProvider` and `BackendRegistry`.
  `ui/dr-ui/src/remote.rs` is now the only file above `dr-sync` that
  names a connector.

`Connection` (an account plus an optional `Secret`) replaces the
credentials-and-user-id pair that was threaded through fifteen
signatures in an order that could be swapped. `Secret`'s inner string is
reachable only through `expose()` and its `Debug` prints `Secret(***)`,
so the indirect leak — a `{:?}` on anything holding one — no longer
compiles into a leak.

Nextcloud is unchanged and keeps every peculiarity: propagating ETags,
chunked upload v2, `oc:fileid`, the `oc:permissions` probe on a refused
PUT, the 423 retry classification, Login Flow v2. Those are what the
capability model exists to serve, not something to hide.

`dr-sync-folder` is the second connector: a local disk, a network mount,
an external drive, or a folder a Nextcloud client already syncs. No
account, no credential — the route that works where no secrets daemon
does. It declares `LocalEtags` rather than claiming propagation a POSIX
directory cannot provide, which costs nothing because 50k `stat` calls
are not 50k PROPFINDs. Identity is a path hash, not an inode: an inode
survives a rename but differs between devices and is reused after a
delete, so two machines would disagree about which photograph a
thumbnail belonged to. Re-deriving a thumbnail is a cost; showing the
wrong one is a bug.

docs/storage.md is the contract — the traits, the four steps to add a
backend, and what each connector declares. ARCH §8.0 and §8.4a, and
FR-NC-13, say why.

dtourolleandClaude Opus 5 af5a13b3f7 Narrow the grid to several people at once, either way
"Show photos" could only ever mean one person. The two questions a photographer
actually asks are "every picture of Anna or Bob" and "the pictures they are both
in", and the second is not reachable by any sequence of single-person filters —
no amount of switching between one person and another finds the frame they
share.

So the filter holds a *set* of people and a mode. `RatingFilter` was already the
right home, as its own doc says: every query path threads it, so the count in
the header and the cells in the grid are narrowed by the same thing, and this
composes with stars, flags and the date range for free.

The union is `EXISTS ... person_id IN (...)`. The intersection counts
**distinct** people per image and compares against the size of the selection —
one subquery rather than one per person, and it does not grow the statement with
the selection. `DISTINCT` is what makes it correct: three faces of Anna in one
frame must not satisfy a filter asking for Anna and Bob, and there is a test
that says so.

Any rather than All is the default. With one person the modes are the same
filter, and adding a second to a union can only ever show more — so a user who
has not noticed the toggle never ends up staring at an empty grid wondering what
they broke. The toggle only appears at two people, because a control that
demonstrably does nothing is a control that teaches the user to ignore it.

Building the set needs no picker of its own: the Identity screen gains "And
also…" beside "Show photos", offered only once the grid is already narrowed to
somebody. Each person is a chip on the filter bar and each chip removes just
that person, so a selection of three can be taken apart one at a time rather
than only cleared wholesale.

`RatingFilter` stops being `Copy`, since it now holds a `Vec`. Every query path
already took it by reference; the casualties were two struct updates and one
`Cell` that becomes a `RefCell`.

484 dr-ui tests pass, including the union, the intersection, that one person
reads the same in both modes, and the repeated-faces trap.

dtourolleandClaude Opus 5 d6380fecc8 Make the People screen a place work can be done
Five faults, all on one screen, and the Slint and Rust halves of each have to
land together.

**Regroup froze the window.** It ran inside the Slint callback, on the UI
thread. It is much faster now, but fast is not bounded — the work grows with the
library, and the one thing that must not grow with the library is how long the
window stops answering. It runs on a worker thread with an mpsc channel and a
250ms poll, like every other long pass in this module, and the button says what
it is doing instead of the window going quiet. Cancellation is dropping the
receiver. Reclustering also prunes the empty groups the previous pass left, so
pressing the button twice no longer fills the rail with "Unnamed (0 faces)".

**The faces were a single row running off the screen.** The comment on the
layout claimed to be a wrapping row; Slint has no flow layout and a
HorizontalLayout does not wrap, so a person with forty faces was a person whose
faces could not be reviewed past the fifth. It is now laid out the way the
library grid lays out thumbnails, with the same arithmetic: choose how many
columns of roughly the requested size fit, then divide the width between them so
the cells fill the row exactly and nothing overhangs.

**The header did not fit a phone.** A 240px name field beside five buttons is
wider than an Android screen — and worse than not fitting, a layout cannot be
narrower than its children's minimums, so the row reported that oversized
minimum upwards and inflated the whole screen. The faces grid is its sibling, so
it would have been measured against a width that was never on the display. The
header is now two rows, the actions sit in a Flickable that scrolls rather than
overflowing, and the rail narrows to 132px on the compact class.

**Strangers crowded out the people who matter.** Most clusters in a real library
are passers-by and other people's guests. "Not interested" sets a group aside;
the rail hides it and says how many are hidden, with one button to bring them
back. Reversible, and never a deletion — see the catalog commit for why.

**A face was a dead end.** Identifying someone and then having no way to see
their photographs is a filing cabinet with no drawer handles. "Show photos"
narrows the library grid to that person and leaves a chip on the filter bar
saying so, which is also how it is cleared. It is a term on `RatingFilter`
rather than a grid scope of its own, exactly as that struct's own doc says new
narrowing terms should be — so the count and the cells are narrowed by the same
thing, and it composes with the others for free. Suggested faces count, not only
confirmed ones, or a freshly grouped person would show an empty grid.

Crops are read from where they are now stored, falling back to cutting one out
of the proxy for faces indexed before that existed.

480 tests pass.

dtourolleandClaude Opus 5 61c4547b9c Make the Identity Manager a peer of the library and develop
It was reachable only from the library header, which made it a side trip
rather than a mode. It is now reachable from develop's header too, beside
the way back, because that is the same kind of move -- leaving this
photograph for somewhere else in the library -- and a screen you can only
reach from one of the other two is not a peer of them.

Leaving returns to whichever screen opened it, and the button says which.
A back button that read "Library" while returning to develop would be
lying about the one thing a back button has to be right about. The
develop session is only hidden, never torn down, so returning to it costs
nothing and keeps the photographer's place.

The header now matches the other two screens rather than using a close
cross: three screens whose headers disagree read as three applications.

dtourolleandClaude Opus 5 10b10569e2 Add the Identity screen
A third top-level screen beside the library and develop, because naming a
cluster and pulling a stranger out of it are tasks with their own rhythm
and need the whole window.

The screen is designed around the clustering being wrong, which is
FR-CULL-10 rather than pessimism: grouping over-merges on siblings, on
parents and children, and on the same person a decade apart. So Split off
sits next to Confirm all rather than behind a menu, the confirm/reject
pair is on the face itself, and a group the system found is drawn
differently from a person the user has vouched for.

Splitting rejects before it confirms. Without that the next clustering
pass suggests the face straight back and the user's correction becomes an
argument they keep having.

Face crops come from the proxies the grid already built, one decode per
image rather than per face -- a group photograph holding six faces of one
family is one JPEG.

Where the calibration is not fitted the screen says confidence is
unavailable instead of printing a percentage that looks measured, which
is FR-CULL-9's rule at the point it becomes visible.

The verdict controls use drawn icons, not tick and cross characters:
ui/icons.slint exists because those render as tofu on Android.

dtourolleandClaude Opus 5 dce1e66746 Show which cell a shift-click is measuring from
The gesture had a hidden operand. A range runs from the anchor — the last cell
plainly clicked — to the cell shift-clicked, and nothing on screen said which
one the anchor was. A user who could not tell where the range was being measured
from had no way to predict what it would take and no clue why a wrong one came
out wrong; often the anchor is not on screen at all, which is itself the answer
to "why did that select so much".

The anchor is marked with an inner ring, drawn inside the selection ring rather
than in a colour of its own: it has to stay legible against a thumbnail of any
brightness, and a hue would read as a second kind of selection. It is an
ordinal, so it marks a row only while the photograph it names is in the loaded
window — off screen it marks nothing, which is the honest answer, and `anchor`
rides in the cell model beside `selected` so both are pushed by the one pass
that already keeps the grid in step with the selection.

dtourolleandClaude Opus 5 7c8e433911 Load the window around the whole view, not around its first cell
The bottom row of the grid was often blank, at a scroll position the user
could sit at indefinitely. Two numbers decided when the loaded window follows
the view, they lived in different languages, and they disagreed.

The grid loaded three screenfuls and Rust held the window still until the
first visible cell was three quarters of the way through them. Three quarters
of three screenfuls is 2.25, and the view itself is one screenful tall — so
the bottom of the screen had already travelled a quarter of a screenful past
the last loaded cell before anything moved. Those rows are not in the model,
so nothing is drawn for them.

The same margin was wrong upward, and exactly so. The window is placed a
quarter of itself behind the view, and the margin then declared the view too
close to the top at precisely that distance: every single row scrolled upward
re-read the catalog, rebuilt all 360 cells and re-queried their badges and
ratings, and so did the row after it.

So the grid now reports what it shows — a screenful, counting the row the
scroll position has cut in half, which `visible-rows` alone undercounts and
which is exactly the row reported missing — and Rust owns the rest: four
screenfuls loaded, placed a quarter back, and moved once the view comes within
half a screenful of an edge of them. One decision in one place, and the test
now walks the view the length of the library and asserts the window covers it
at every step.

dtourolleandClaude Opus 5 fa4ad6e2d6 Drag the date range on the axis it is chosen from
The range could be turned on with a finger and not aimed with one. Its two
ends were typed as `YYYY-MM-DD` into 108px fields behind a soft keyboard, to
name days already drawn on the axis a thumb away; and the chip that seeds them
takes its span from the timeline's zoom and pan, which are a wheel and a middle
button. A touch screen has neither, so on Android the filter was a switch with
no aim.

The band is now on the timeline. Two ends with grips, dragged along the bars,
released to filter — the histogram was already how a period is found, and this
makes it how a period is stated. Both ends snap to whole days, which is what
the typed fields mean, what `show_range` reads back out, and a floor under a
range dragged shut. The fields stay for what dragging cannot do: name an exact
day, and say in words what the range is.

For that to work the axis had to stop following the range. Redrawn to the band,
it moved the ground under the very handles doing the narrowing, and there was
nothing outside the range left to widen back into.

While there: a fixed number of equal bins instead of calendar buckets. Between
one calendar unit and the next the bar count is free to wander by a factor of
twelve, so zooming in halved it two steps out of three — the same picture drawn
wider until it jumped back to fine. Equal bins also include the empty ones, so
a bar's position on the track and the date under it are finally the same
quantity; before, a library with gaps drew a February six months wide and the
marker, the band and a click all pointed somewhere else. The count is a
setting, 32 or 64, because the right answer is a question about the screen.

Three things a selection needed and did not have.

**Seeing it.** The count existed — "12 selected" — in the header row, which
scrolls sideways. On a tablet it sat past the right-hand edge along with every
button beside it, so a selection was something you could make and then not
see. A selection you cannot see is one you act on by accident.

**Putting it down.** The only way to clear one was "Done", which also leaves
select mode — so after filing forty photographs the next forty began by
re-entering a mode the user had not meant to leave. Clearing is now its own
action and keeps the mode.

**Filing it somewhere new.** Making a collection of a selection took four
steps: create one, find it in the tree, select the photographs again because
creating it changed the scope, then add them. It is one press, which is how a
selection is usually meant — it is gathered *because* it is going somewhere.

The new collection is created at the top level rather than inside the current
scope, unlike the tree's "+". A selection can be gathered from anywhere,
including across collections, so filing it under whichever one happens to be
open would put it somewhere its contents did not come from. It opens straight
into its name field, for the reason `collection_new` already does: the
placeholder name is nobody's choice, and making the user find the rename
afterwards is asking them to finish a job we started.

All of it on its own strip beside the date range's, appearing only while there
is a selection — the third control this session that was invisible for being
put in a row that scrolls.

Third attempt at one control, and each failure was a different reason it could
not be seen.

It narrowed to the whole library, because it took its span from a timeline zoom
that is zero until someone zooms. The fields that fixed that went into the chip
row, which scrolls sideways, so they sat past the right-hand edge. And moving
them "below the chips" put them inside the same `Rectangle` — which stacks its
children at the origin rather than laying them out, so they were drawn over the
chips inside a strip 34px tall, unconstrained in width and clipped in height.

A `Rectangle` is not a layout. The row is a sibling of the chips' strip in the
header's `VerticalLayout` now, with a height of its own and the width of the
window: two 108px fields, a "to", and a warning when what was typed is not a
date — about 354px, against 768 on a tablet in portrait.

Left-aligned and inset by the same gap the chips use, so the two rows begin on
one vertical line instead of a few pixels apart.

dtourolleandClaude Opus 5 db43d8ec8b Put the range's ends where a tablet can see them
"Limit to range" looked broken a second time, for a second reason. The ends
were added to the filter chip row, and that row scrolls: its own comment
records that fourteen chips do not fit across 768 logical pixels, "so that is
every tablet in portrait". Two date fields and a caption went straight past the
right-hand edge, into the part of the row that has to be panned to.

So the fix for a control that appeared to do nothing was itself invisible, and
pressing the chip still looked like it did nothing.

They have their own line now, below the chips and outside the Flickable, and it
exists only while a range does. Nothing competes with it for width, and nothing
has to be panned to reach it.

dtourolleandClaude Opus 5 4b7648082e Let a date range be stated, and draw the axis at the scale it deserves
"Limit to range" did nothing, and the reason was not visible from the button.
It took its span from the timeline's zoom, which is zero until someone zooms —
so `zoomed_span` returned the whole library and the filter narrowed to
everything. The chip lit up and the grid did not change.

The range has ends now, shown and typed as `YYYY-MM-DD`. Seeding them from the
timeline is kept, because zooming to a fortnight and pressing the chip is the
fast path; the fields say which fortnight it landed on and let it be corrected.
Ends given backwards are swapped rather than refused — there is exactly one
range between two days — and the closing day is included, since "to the 5th"
means the whole of the 5th and a range ending at its midnight contains none of
it. `parse_date` refuses anything that is not a date rather than guessing at an
order, because the alternative is a library silently filtered to a span nobody
asked for.

The axis then follows the range. It used to keep drawing the full extent while
a range was on, because it was the only way back out; the typed ends are the
way back out now, so it is free to show what was asked about.

And bucket size is chosen by how many bars it makes rather than by fixed
cut-offs. Each zoom step halves the span, so under thresholds the bar count
halved with it until a boundary was crossed: fifteen years went 15 bars, 8,
then 46, 23, 11, and finally 6. Zooming in made the picture coarser, which is
the opposite of what zooming is for. Aiming at forty bars keeps the count in
the same neighbourhood at every level, and the test asserts the property
directly — halving a span never coarsens the bucket.

dtourolleandClaude Opus 5 85aae25d0f Let the header readouts shrink instead of pushing the controls off screen
Found uncommitted in the working tree and committed as its own change rather
than folded into the sync work beside it: the three header readouts gain
`overflow: elide` and `horizontal-stretch: 1`, which is what actually lets a
Text shrink under pressure in Slint. Without the stretch they kept their full
natural width and pushed the sidebar toggle and the More button past the right
edge on a narrow window, reachable only by knowing to flick-scroll.

dtourolleandClaude Opus 5 b1bf68022d Do not offer an import where one cannot be done
The Import button went into the library header unconditionally, so an Android
user got a page that opens, finds nothing, and cannot be pressed — worse than
no page at all, because it reads as broken rather than as absent.

`dr_plat::imports_supported()` answers the question the interface actually has,
which is not "did we find a volume". An empty list on Linux means plug one in;
false here means it cannot be done on this device however hard the user tries.
It is false on Android for two reasons that both have to be fixed before it
changes: there is no mount table to read and no path to type, and nothing
implements WritableStorage except LocalStorage.

The button is hidden rather than disabled. The buttons beside it come and go
with the selection — unavailable now, available in a moment — where this one
never will be here, and a permanently disabled control teaches the reader that
the row lies.

What this gates is the interface, not the engine. dr-ingest takes storage
traits and never a path, and cross-compiles to aarch64-linux-android today; it
should need no changes when a SAF implementation lands.

dtourolleandClaude Opus 5 49be1fe354 Give the library somewhere to type a keyword
A sheet over the grid, opened from the header beside "Add to collection" —
deliberately the same card, scrim and dismissal as the filing sheet, because
they are the same gesture applied to two kinds of label: pick the photographs,
then say what they are. A user who has filed a selection already knows how this
works.

A word the whole selection carries, a word only some of it carries, and a word
none of it carries are three visibly different marks. Half-applied shown as
applied would be a lie about photographs the user cannot see from here, so a
partial keyword draws a dash and says "3 of 12" beside it. Tapping a dash
completes the keyword rather than removing it, which is what it means nine times
in ten, and the tenth is one more tap away.

The vocabulary is answered against the selection in Rust and pulled when the
sheet opens rather than pushed on every selection change — the selection moves
on each arrow key and the sheet is shut for almost all of them.

Assign and unassign travel by name, so a word typed into the field and a word
tapped in the list are one path rather than two, and the sheet never has to
invent an identity for a keyword that does not exist yet.

One gap, commented at the call site: unlike a star or a flag, a keyword is not
queued to the image's sidecar, because the sidecar format has no field for one.
So it reaches the user's other devices through the catalog merge, and a deleted
catalog loses keywords where it would keep ratings.

dtourolle 3085ec4d2e Leave the stars on screen on a touch device
**Hover is not something a finger does, but Slint reports it anyway.**
`has-hover` goes true for any pointer event carrying a position, a touch
press included, and false again on the `Exit` that follows the release.

So the rating strip did appear on a tablet — for exactly the length of a
tap. It flashed on under the finger, vanished as it lifted, and the tap
carried on through to the cell and opened the photograph. An unjudged
frame could not be rated from the grid at all. The previous fix stopped
the strip disappearing when a *pointer* moved onto it; this is the same
symptom with a different cause, and hover was the wrong signal in the
first place.

The strip now stands open where the session is a touch one. That is
seeded from the platform rather than inferred, because inference needs a
press to reach a cell and a quick flick never delivers one — the Flickable
claims the gesture before the delay it would forward after — and a
control that only appears once the finger is down has appeared too late
to aim at. The grid still latches on the first non-zero touch id it sees,
which is what covers a touchscreen on the desktop.

One-way on purpose: a tablet with a mouse plugged in keeps the strips
once touched, which is the harmless direction to be wrong in. The
alternative is chrome that comes and goes as the user changes hands.

dtourolle 2fba685e16 Make a pinch zoom the grid and nothing else
Two faults left over from making the gesture reach the grid at all.

**It still opened photographs.** Checking the finger id stops the
synthetic release Slint emits when the *second* finger lands, but not the
other end of the gesture: lifting one finger of two leaves the other one
down, and Slint replays that survivor as a fresh `Pressed` on whatever is
under it — which is how it hands the pointer back to ordinary handling.
Under it is a cell. So the cell was selected, and lifting that last finger
was a complete, well-formed click on the same finger that pressed. No
part of the event stream distinguishes it from a real tap, so the grid now
remembers that a pinch just happened: a latch raised when the gesture
starts and lowered a beat after it ends, during which cells take neither
presses nor clicks.

The press that *opens* a pinch is undone rather than suppressed — it has
already happened by the time a second finger makes it a pinch. Undoing it
has to be exact, or a cancel that restored the selection but left the
anchor moved would make the next shift-click select a run from a cell
nobody pointed at, so capture and restore are a tested pair.

**And it was not smooth.** Two reasons. The pinch was thresholded into ±1
steps of 25%, so the grid lurched and then sat still; it now takes the
ratio since the last update and tracks the fingers, with the drawn cell
still landing on whole column counts because the columns divide the
width. And `zoom-cells` was the one geometry change still reloading
inline — a full catalog re-read, 360-row model rebuild and thumbnail
batch per step, on the thread drawing the frame. It goes through the same
settle timer as the rest now.
2026-08-21 22:03:46 +02:00
dtourolle 6ae0af3f72 Swipe up in develop for the photo roll
Develop opens one photograph. The grid handed over a path and nothing
else, so `index` and `total` were pinned to "1 of 1" on the way in and the
only route to the next frame was back to the library, find your place,
tap again. Fine once; intolerable through a set of forty, which is the
situation the develop view exists for.

The roll is the grid's already-loaded window along the foot of the
canvas. Swipe up to bring it out, swipe down to put it away — the sheet
gesture, already in the hands of anyone who has used a phone — and a
handle is drawn at the edge so the gesture is discoverable rather than
folklore, and so a pointer, which has no swipe to make, has a way in.

`SwipeGestureHandler` wraps the strip rather than sitting over or under
it, which is what it is built for: it delays a press the way a Flickable
does, forwards it to the children if no swipe develops and claims it once
one does, so a tap reaches the thumbnail and a drag does not. It covers
only the band along the bottom — above that, a drag still belongs to the
photograph, for panning and for the crop.

Picking goes through the same path a cell click does, so the outgoing
edit is persisted before the next image loads. The strip marks what is
open and scrolls to keep the mark in view.

The position readout now says where in the *library* the open photograph
sits rather than "1 of 1". Set after the open rather than before, since
the generic open path resets it — and given as the library ordinal, not
the row in the loaded window, which is an artefact of how much has been
paged in and would jump about as the window moves.
2026-08-21 21:10:44 +02:00
dtourolle c72f197880 Stop a row of buttons deciding how wide the grid is
**A Slint layout cannot be narrower than its children's minimums.** Given
less room than they need it lays them out at those minimums, lets the row
run past the edge — and reports the oversized minimum upwards.

That second half is what made this more than cosmetic. The header, the
filter chips and the grid are siblings in one VerticalLayout, so the
widest row's minimum became the whole view's minimum: `LibraryGrid` was
laid out wider than the window. The grid then measured itself against
that inflated box and sized its columns to fill space that was off the
screen, so the right-hand column was cut by the edge no matter what the
tiling arithmetic did. Fourteen filter chips do not fit across 768
logical pixels, so that was every tablet in portrait.

It also explains why opening the collections sidebar did not reflow the
grid. The view was already pinned at a minimum wider than the window, so
taking 232px away for the sidebar could not shrink it — it just clipped
more of it.

Each of those rows is now a horizontal Flickable. A Flickable's own
minimum is nothing, since it exists to be smaller than what it holds, so
none of them can inflate anything — and the controls past the edge became
reachable instead of merely absent. Applied to all four: the library
header, the filter chips, the compact action row disclosed by "More", and
the develop strip.

dtourolle 12a457b8d0 Tile the thumbnails to fill the width
The cells were drawn at whatever pixel size the class asked for and the
remainder was left as a bare strip down the right-hand side — up to one
short of a full column of nothing, which on a phone is a quarter of the
screen.

It also had the two quantities depending on each other the wrong way
round. The column count was derived from the fixed cell size, so the two
could disagree about how much room there was and the last column could
start inside the viewport and end outside it.

Solving for the cell removes both at once. Pick how many columns of
roughly the requested size fit — rounded, not floored, because the size
class is a request rather than a measurement and a width nine tenths of
the way to another column should take it — then make those columns share
the width. `columns` cells and the `columns + 1` gaps around them come to
exactly the grid's width, so there is no remainder to strand and nothing
can overhang.

The size class still decides what the user gets, since it is what the
column count is chosen from. It just no longer dictates the pixel, so the
cell flexes a few percent either way to make the row come out even.

dtourolle 4d8196174c Let the grid be pinched instead of opening an image
Two separate faults, both only reachable with a second finger.

The gesture never arrived. `ScaleRotateGestureHandler` was sized `100%`
inside the Flickable, which is the Flickable's own height, not its
viewport's — so the handler was one screenful tall at the top of a
viewport thousands of rows long. A pinch is delivered to whatever lies
under the midpoint of the two fingers, so it landed on the handler only
while the grid was scrolled to the very top and found nothing anywhere
else. Sized to `viewport-height` now, exactly as `zoom-catcher` above it
already is.

And the attempt opened a photograph. When a second finger lands Slint
closes the first one's gesture by synthesising a `Released` at its
position — that is how a Flickable is persuaded to let go of a scroll it
has already claimed. A TouchArea cannot tell that release from a real one
and fires `clicked`, so every pinch opened whichever image the first
finger was resting on.

The finger id separates them: the synthetic release carries the id of the
finger that *arrived*, never the one that pressed. `clicked` fires before
the pointer event that names the finger, so it now only raises a flag and
the `up` handler decides. A mouse reports 0 for both, leaving the desktop
path exactly as it was.
2026-08-21 20:30:20 +02:00
dtourolle 892da2662a Keep the stars on screen long enough to click one
The rating strip was a sibling of the cell's TouchArea, declared after it
so that hit-testing reached the stars first. That half worked: a star
click set a rating without also opening the image.

The other half did not. Hover is tracked per TouchArea, and Slint sends
`Exit` to any item that drops out of the hit path. The strip taking the
pointer is exactly that — `cell-touch` left the path, `has-hover` went
false, and `show-empty` went with it. On an unrated cell the stars are
drawn *only* on hover, so they vanished as the pointer arrived at them;
the click then landed on the cell behind and opened the image. Reported
as "the star menu disappears when I click on an image", which is
precisely what it does.

Nesting the strip inside `cell-touch` keeps both halves. Children are
hit-tested before the element containing them, so a star still wins the
click and still ends the walk before `cell-clicked` runs. And an ancestor
stays on the item stack: it gets no `Exit`, and while a child holds the
grab it is handed the event filter and never the event. Hover therefore
holds for as long as the pointer is anywhere in the cell.
2026-08-21 20:29:10 +02:00
dtourolle 76a751f125 Measure the grid against the grid, not the whole view
`cell-size`, `columns` and `visible-rows` were all derived from the
LibraryGrid's own width and height. The cells are not drawn in that box:
the capture-time axis is a sibling of the grid, 96px of it, and the
header takes another 44px off the top.

So `columns` counted the timeline as room for thumbnails and fitted one
more column than there was space for. The last column started inside the
Flickable and ended outside it — clipped, with no sideways scroll to
reach it. At the 180px size class on a phone in portrait the timeline is
a quarter of the screen, which is most of a column.

`visible-rows` was wrong the same way and fed `capacity`, so every window
over-fetched by the ratio of the header to the viewport.

Both now read `grid-area`, the layout the cells actually live in. That is
a descendant, and reading a descendant's geometry is the shape that
causes binding loops elsewhere in this UI — but not here: nothing derived
from these feeds back into the layout. The cells are placed absolutely
inside the Flickable and a Flickable's layout constraints are a bare
`stretch: 1` that its viewport cannot influence.

The library could be narrowed by rating, flag and availability, but not
by when a photograph was taken — so finding a fortnight meant scrolling
to it and holding position.

The range rides on `RatingFilter` for the reason `local_only` already
does: every query path threads that one struct, so the count in the
header cannot claim a total the grid does not draw. Undated images are
excluded whenever either end is set — they cannot be inside or outside a
span, and drawing them made the range look as though it had not applied.

Taken from the timeline rather than typed into two date fields. Finding
the period is what the histogram is for, and having found it the user
should not have to read the dates off the axis and key them back in.
The histogram keeps drawing the full extent while the range is on, or
there would be nowhere to widen back out from.

dtourolleandClaude Opus 5 dea826811e Render a blown highlight white instead of magenta
Every clipped sky came out bright pink. Measured, not guessed: developing
_MG_8596.CR2 and looking at the export, the subject renders correctly and only
the saturated region is wrong.

A fully clipped pixel reaches the shader as (1, 1, 1) — three photosites that
stopped counting, carrying no colour at all. The as-shot multipliers are not
neutral, so balancing sends it to (1.93, 1.00, 1.68) on this body, and the
camera matrix turns that into R 2.88, G 0.51, B 2.03. Red and blue clip at
one; green, whose matrix row is far less positive-heavy, does not. Red and
blue high with green low is magenta.

Nothing upstream was at fault, which is why the two previous attempts missed
it: the white balance is correct, the matrix is correct, and the sensor
normalisation is correct. The input simply was not a colour, and correct
arithmetic on a non-colour produces a confident wrong answer.

So saturation is detected before the balance is applied — the last 1.5% of
range, smoothstepped rather than switched, because a hard threshold draws a
visible rim around every highlight and a backlit edge on skin is where that
shows. Above it the pixel is pulled to the neutral of its own brightness, so
it keeps its luminance and loses only the cast.

Verified end to end on the file itself: the sky is white, the skin, the black
dresses and the stone are unchanged.

dtourolleandClaude Opus 5 d913e50948 Select photographs with a finger, and take a collection with you
Two things a tablet could not do. Both existed for a pointer and had no
touch form at all, which on Android meant the collection sidebar was
somewhere to look at rather than somewhere to file into.

**Selecting more than one.** Ctrl-click and shift-click are the only ways
into a multi-selection, and touch has neither. Holding a cell now enters
selection mode, where a tap toggles — reported to Rust as a ctrl-press, so
it goes through the same `apply_press` as everything else rather than
growing a second copy of the selection rules. A double tap takes the run
between where selecting began and there: the touch form of shift-click,
and the reason the anchor from *before* the double tap has to be
remembered, since both of its taps move the anchor onto the cell being
tapped. A "Select" button does the same thing where a gesture would go
undiscovered (FR-UI-4).

**Filing without a drag.** A one-finger drag beginning in the grid belongs
to the Flickable that scrolls it — that is the arbitration working, not a
bug to route around — so the selection can now be filed from a sheet
listing the sidebar's own rows. Copy by default, as the drag has always
been; moving out of the collection being shown is a switch, because it is
the one that takes something away.

**Taking a collection offline.** The machinery was there and reachable only
by scoping the grid to a collection and finding a button behind a
disclosure. Holding a collection's name now asks the question directly, and
the tray on a row and the header button ask the same one — three
affordances doing two different things is how a user comes to avoid all
three. The question is asked rather than a toggle flipped because both
answers are expensive: one downloads gigabytes, the other deletes them, and
the counts and sizes go in the buttons where they are read before the tap.

`Cache::release` is new and is the destructive half `unpin` deliberately is
not. "Remove the local copies" is asked by someone whose device is full,
and withdrawing a promise while leaving the bytes for a future eviction to
notice is not an answer to it. It unpins before forgetting, or the next pin
fetch would dutifully download everything it just deleted.

The sidebar's trays read `tier_actual`, never `tier_desired`: the question
is whether these will open on the aeroplane, and a pin whose download has
not run yet answers no.

dtourolleandClaude Opus 5 7d3c8c521f Export a whole selection, on a thread that is not the interface's
The export button rendered, resampled and encoded a 24 MP frame on the UI
thread and the window was dead for all of it. That was written down as a known
compromise, on the grounds that a batch is what makes the wait intolerable
rather than merely noticeable. This is the batch, so the compromise comes due.

The grid's selection now exports (FR-EXP-7). A worker thread takes a clone of
the `GpuContext` — an `Arc` pair over a device and a queue — and opens each
photograph for itself: fetch, sidecar, decode, demosaic, render at full size,
resample, sharpen, encode, write. Nothing of that touches the interface, which
keeps drawing throughout, and the progress goes where every other background
job's does: one row in the activity register, with a count and a bar.

Why the worker does not borrow the session it could have had. A
`DevelopSession` owns the `AdjustPass` the canvas renders from, so handing it
to a worker would stop the develop view drawing for the length of the batch —
the same freeze, moved. Opening a session per image instead costs a
`Demosaicer` and an `AdjustPass` each time round, and the pipeline cache is
per-pass so the composed shader is recompiled per image rather than once for
the run. Against a full-resolution decode, render and encode that is a few
percent, and it keeps this file out of the pipeline `develop` owns. A reusable
export pass is the obvious next economy if a profile ever says so.

The open image is the exception, and it is why the develop button is not simply
a one-image batch. Its edit lives in the interface's session and may not have
reached a sidecar yet, so a worker that re-opened the file would export the
saved version rather than the one on screen. That frame is therefore rendered
by the caller and handed over as `Source::Rendered`; everything after the
render — the Lanczos reduction, the encode, the write, which is the larger half
of the wait and all of its variance — still leaves the UI thread. So the
develop export is no longer synchronous, but it is not fully off-thread either,
and the doc comment says so rather than claiming otherwise.

Cancellation (NFR-ARCH-3) is an `AtomicBool` read between stages, and the
export button becomes the cancel button while a run is live — a batch that
could only be stopped by not touching the selection would be a trap. Waits on
another worker use `recv_timeout` rather than `recv`, so a cancelled batch
sitting on a forty-megabyte download gives up within 100 ms instead of when the
transfer finishes. The honest bound is worse than that: a frame already in
render has no interior stopping point, so the worst case is one image. Closing
that needs the render itself to become interruptible, which is NFR-ARCH-2's
scheduler and not a finer poll here.

Failures are per image and typed (NFR-ARCH-4). One unreadable body, one folder
that cannot be written, one server that went away — each is a message on the
channel, a line in the log, and a count in the summary, and the batch carries
on. A run with any failure keeps its row until it is cleared, because that is
the row somebody came to the list to find; a cancelled run does not, because
they asked for it.

Two collisions that look alike and are not. `CollisionPolicy` is the user's
answer to "a file of this name was already there", and Overwrite is a fine
answer to that. It is not an answer to "the frame I exported four seconds ago
was also called this" — two folders in a library each holding an IMG_0001 is
ordinary — so a name the run has already issued is always stepped past whatever
the policy says about the folder. Both halves are held by tests.

Supporting changes, each smaller than it sounds. `open_session` comes out of
`load_bytes` so the worker shares the JPEG-versus-RAW routing rather than
carrying a copy that would drift; the half that builds a `slint::Image` stays
behind, where it belongs. `LibraryController::selected_image_paths` answers
from the catalog rather than from the loaded window, because selection is by id
and survives a scrub — a selection made before scrolling routinely names
photographs no row holds. `cache_context_for` takes an id for the same reason,
so a batch reads the originals cache instead of re-downloading three hundred
files. `format_date` is shared so `{date}` and the timeline agree about what
day a photograph was taken.

Left undone, deliberately: the batch is sequential, where FR-EXP-7 asks for all
available cores. Four full-resolution frames in flight is tens of megabytes
each and a straightforward way to exhaust a tablet, and the GPU is shared with
the interface in any case. Also undone: exporting with a chosen preset rather
than the current export settings — that is FR-EXP-5's machinery, which does not
exist yet.

dtourolleandClaude Opus 5 e00c99b864 Let a photograph leave: an export button, and a cache to leave from
dr-export could turn a frame into bytes and nothing could ask it to. This is
the button, and the place the bytes go.

**Everything is staged first.** An export bound for the server is written to a
local outbox and uploaded afterwards; offline is not a special case, it is the
same path with a drain that finds the server absent. Doing it the other way —
upload directly, stage only on failure — makes the failure path the one that
is rarely exercised and always broken, and a network drop mid-batch leaves
some exports existing and some not with nothing recording which. Staged first,
an export is finished the moment it is written and the upload is a promise
kept later.

The outbox sits beside the catalog rather than under the cache. dr_catalog's
cache already draws that line: passive entries are a convenience and go under
LRU, pinned ones are a promise and never do. An export awaiting upload is a
promise — the user was told it succeeded — and sweeping it for disk would
destroy the only copy. Bytes are written before the destination record, so a
kill between the two leaves an orphan the drain ignores rather than a record
pointing at nothing.

The status line says "Queued for Exports/2026", never "Exported to Nextcloud",
until it has actually landed. There is a test asserting that wording, because
the tempting shorter sentence is a claim the app cannot keep.

The drain runs on the sync pass, before the shards: a thumbnail shard can be
rebuilt from the originals and the catalog is an index, but a queued export
exists nowhere else.

`DevelopSession::render_for_export` renders the framed size rather than reusing
the frame on screen, which is deliberately viewport-sized (FR-DSP-1) — encoding
that would hand the user a soft, screen-sized file with nothing to say anything
had been lost (FR-EXP-9).

One compromise, recorded rather than hidden: the export runs synchronously on
the UI thread, so the window is unresponsive for the few hundred milliseconds
a full-resolution render and encode takes. Moving a DevelopSession and its GPU
pass to a worker is a larger change than one button earns, and it is batch
export that makes the wait intolerable rather than merely noticeable.

Still missing: the Nextcloud folder *picker*. The destination is typed into
Settings for now. `FolderBrowser` in launch.rs is already the reusable model
for it — it browses a remote tree and nothing about it is specific to choosing
a library root — but wiring it into the settings page needs a listing worker
and browser UI there, which is its own piece of work.

Carries in-flight work from a parallel session — presets, the develop copy and
paste, and the node schema's `presentation` and `enum` support. One misplaced
callback in settings_ui.rs is moved from `render` to `wire`: registered in
`render` it borrowed a `&SettingsController` into a 'static closure and would
not compile, and that file's own docs say render pushes properties while wire
connects callbacks.

992 tests pass, clippy and fmt clean. Traceability 48.3% -> 51.0%.

dtourolleandClaude Opus 5 e7130ff891 Give the library header somewhere to put six buttons
A tablet in portrait is 1920 physical pixels at density 400 — 768 logical,
which is below the 820 breakpoint, so the library was already taking the
compact layout. The compact header simply was not compact: one flat
HorizontalLayout holding a menu button, a title, three status readouts and
six buttons.

Slint's HorizontalLayout has no wrap and no overflow. Given less width than
its children want it shrinks each to its minimum and lets the rest run past
the edge, so "Change library" arrived as "Change li…", the readouts elided to
nothing useful, and the row overflowed anyway.

The six actions move into a `HeaderActions` component drawn in one of two
places: inline in the header when expanded, and in a disclosure row under it
behind a "More" button when compact. One component rather than two copies,
because the alternative is six buttons with their visibility rules and
callbacks written twice, and the copy that rots is the one behind a
disclosure nobody opens while testing.

The row closes itself when the window widens, so rotating to landscape does
not leave a stray toolbar behind. "More" is a word rather than an ellipsis
glyph: "⋯" sitting in a header of elided labels reads as one more truncation,
which is the failure this change exists to remove.

`LibraryGrid` takes `expanded` to decide, from the window width rather than
the device (FR-UI-1) — so a narrow desktop window gets the same treatment.

dtourolleandClaude Opus 5 65e6a96a65 Say what the application is doing, in one bar and one list
Every background job reported into a window property of its own —
library-thumbs-done, library-pin-total, library-syncing — which only the
grid ever read. A pin download that outlived the view it was started from
drew nothing at all once the user opened an image, and there was no answer
anywhere to "what is this busy with", because the answer was spread across
eight properties nothing collected.

They report to one register now (ui/dr-ui/src/activity.rs). It publishes an
aggregate, which draws a three-pixel bar across the top of the shell in
every view, and a row per job, which the settings page lists: scans,
thumbnail batches, pin and open downloads, sidecar uploads, the sync and
the trash. Failures stay on the list until they are cleared; routine
successes do not, or a scroll would bury them.

The handle removes a still-running job when it drops, so a worker that dies
mid-transfer takes its row with it rather than leaving the bar sweeping for
the rest of the session.

Also carries in-flight work from a parallel session — the drawn icon set
and the dr-pipeline ops split. dr-pipeline's build script does not compile
at this commit; ui/dr-ui does, with clippy clean and its tests passing.

A cull is thousands of decisions. The grid already bound 0-5, P, X and U so
the judgement itself needs no mouse, and then made the photographer reach
for one to move to the next frame — which is most of the gesture, most of
the time. Arrows now move a cursor, shift+arrow extends the selection,
Home/End and PageUp/PageDown cover ground, and Return opens what the cursor
is on.

The cursor is a library ordinal, not a row of the loaded window. The window
is a few screenfuls around wherever the user is looking, so a cursor held as
a row would stop at its edge or keep counting into cells belonging to other
photographs; walking out of the window reloads it around the new position,
exactly as scrolling does. This is the argument the selection already made
by keying on ids rather than rows.

The anchor had that fault for real: it was a window row, so a shift-click
after a scroll extended from whatever image had since drifted into it. It is
an ordinal now, and apply_press takes the window's offset to map between the
two. A range longer than the loaded window truncates to what is loaded,
since selection is by id and an image the catalog has not been asked for has
none.

The pointer and the keyboard share select_row so the two cannot drift apart.
The one deliberate difference: a plain arrow collapses the selection onto
the cursor, where a plain click on an already-selected cell leaves it alone
— that exception exists so a multi-image drag can start from one of its
members, and there is no drag behind a keystroke.

The grid scrolls to the cursor only when the cursor leaves the viewport, and
then by as little as will do it. Reusing the scrub's seek() would put the
cursor's row at the top on every press, which makes a row unreadable as you
walk along it.

dtourolleandClaude Opus 5 94a2686dcb Fit the interface to the system bars, the finger and the back key
Four faults that only show on a device, and one that was hiding on the
desktop too.

The system bars. Target SDK 36 forces edge-to-edge, so the window spans
the display and the develop status strip was drawn underneath the clock
and the wifi icons. Slint already computes the inset from Android's
OnApplyWindowInsetsListener and exposes it as Window.safe-area-insets;
nothing read it. The four views now sit inside a shell placed within the
safe area. Every inset is zero on the desktop, so that layout does not
move.

Sliders under a finger. A Flickable steals any gesture that drifts more
than 8 logical pixels along its scrolling axis within half a second of
the press, and it steals it by cancelling the child. ParamSlider's axis
test correctly declined to claim vertical drags, but nothing told the
Flickable to stand down once a drag was claimed — so an adjustment would
start moving and then be taken away mid-motion. A mouse holds a
horizontal line closely enough to stay under 8px; a finger does not,
which is why these worked on the desktop and not on the tablet. The
claim now sets `interactive: false` for the rest of the gesture.

The tone curve had the same fault and worse: its points are dragged
vertically, which is the Flickable's own axis, so every drag was stolen
— on the desktop as well.

The back gesture. Nothing handled it, so back closed the application
from anywhere in it. Android delivers it as Key.Back to the focused item
and bubbles it up the ancestors, which is the second reason the shell
wraps the views rather than sitting beside them. The order is innermost
first: settings, then crop, then zoom, then develop to the grid, then a
collection scope. Answering false at the top of the stack leaves Android
to close the activity, as it does for every other application there.
Escape does the same on a keyboard.

back_step is a pure function over a flat NavState so the ordering can be
tested without a backend: which of two states is left first is the whole
of the feature, and it is the part that is easy to get subtly wrong when
spelled out in nested ifs over live properties.

Develop's canvas now takes focus on show. Without it the arrow keys did
nothing until the canvas was clicked, and Key.Back had no focus item to
bubble from.

Panels that close. The collections sidebar and the develop column are
collapsible from the grid header and the status strip. The layout class
now supplies only the default: a panel closed to see more of a
photograph stays closed while the window keeps its shape, and the choice
is dropped when the class changes, because rotating a tablet asks a
different question from the one answered in landscape. IMAGE became a
Section, being the only group in the column that could not be put away
and the one whose content is read first and needed least.

Pinch to zoom on the develop canvas, anchored on the midpoint between
the fingers (FR-UI-4). The wheel is the desktop's answer and there is no
wheel on a tablet.

The develop status strip was 28px against the 44px headers on the
library and settings pages either side of it — the one screen where a
way out has to be found was the one drawn smallest. All three now agree.

Verified with cargo test -p dr-ui (192 passing, 6 new), clippy at
-D warnings, and an arm64-v8a release build packaged to an APK.

Fills in `image_cache`, which the previous commit's "On this device" filter
read but nothing wrote. Also carries in-flight work that shared these files:
the Android TLS root store, the settings page, and a regenerated
traceability report.

# Two populations, deliberately separate

An original is kept here for one of two reasons, and conflating them produces
the exact failure the feature exists to prevent.

**Pinned** originals were asked for. Pinning a collection before a trip is a
promise, so pinned rows are never evicted and never counted against the
budget — a cap that could silently delete a pinned trip would make pinning
worthless, because it could not be relied on without checking.

**Passively cached** originals are a side effect of working: develop already
downloads the whole file, so keeping it costs no bandwidth and saves the
entire transfer next time. This population is what the budget bounds, evicted
least-recently-used, because it otherwise grows until a day of culling fills
a disk.

Sharing one budget would let a large pin starve the passive cache, or let
browsing evict a pin. They are separate.

# What was built

`dr_catalog::cache` owns the bookkeeping — held tier, size, last use, pinned
— and writes the bytes; deciding to download stays with the caller, which is
what keeps a crate with no network out of the network's business. Files are
written to a temporary and renamed, so a dropped connection cannot leave a
truncated file recorded as a complete original. They are named by image id,
not filename: `Photos/IMG_0001.CR2` and `Trips/IMG_0001.CR2` are different
photographs, and a flat cache keyed on the name would serve one for the other.

`spawn_full_fetch` became read-through. A hit is a disk read; a miss stores
what it downloads and enforces the budget. A cache that cannot be opened is a
miss, not a failure to open the photograph.

Pinning writes intent — `tier_desired` — without downloading, so the button
responds immediately, and `spawn_pin_fetch` fills it in sequentially
afterwards. Sequential because these are tens of megabytes each: the lanes
that make the thumbnail sweep fast buy little against one connection's
bandwidth and cost a great deal of memory. A pin interrupted by a lost
connection resumes from where it stopped.

Schema v5 adds `pinned` and `path`. `pinned` is a column rather than something
inferred from `pinned_by_rule`, which is ON DELETE SET NULL and so cannot
answer for an image whose rule was deleted. A v4 catalog migrates in place;
existing rows default to unpinned, the safe direction.

The budget and "keep opened originals" come from the settings page rather than
a constant, and are applied at startup rather than only on change — a cache
capped at 2 GB last session would otherwise spend this one filling to the
default. Turning off keeping leaves what is already cached readable: those
bytes are paid for, and refusing them would re-download images sitting right
there, including pinned ones.

Also removes a doubled `#[test]` introduced in the previous commit.

dtourolleandClaude Opus 5 cd75e5a4c6 Run the library from local data when the server is unreachable
Also carries in-flight work that shared these files: the zoom structure-key
fix in the adjust pipeline, nearest-neighbour filtering past 1:1, the
timeline scrub marker correction, the 423-Locked retry in the metadata
sweep, and the thumbnail size-class migration.

# Offline mode (FR-CAT-9)

The app previously assumed the server was reachable and treated its absence
as a series of unrelated per-operation failures. A launch without a
connection produced an empty grid, even with a complete catalog on disk and
every thumbnail already in the shards.

Reachability is now inferred from traffic the app was already making, rather
than probed for. `RemoteError::indicates_offline` draws the line that makes
this possible: a dead connection is offline, a 403 or a 500 is not — the
server answered, so blanking the library over one forbidden file would be a
worse error than the one being reported. `Reachability` turns those outcomes
into a state, so a library browsing happily never issues a probe at all.

Going offline takes one failure, because the user is already experiencing it.
Coming back requires evidence — a completed scan or a fetched thumbnail —
with a capped exponential backoff behind the manual retry, so twelve sweep
lanes failing together do not schedule twelve immediate probes.

What keeps working: the catalog opens even when the scan that normally
provides it failed, so the grid fills from the last successful scan.
Thumbnails come from the shards. Rating, flagging and collecting are catalog
writes that never touched the network. What stops is opening an original that
was never stored locally, and it now says so in those words instead of
reporting "network error: connection refused" over a photograph.

Work that is pure network is refused rather than left to fail slowly: the
metadata sweep, derived sync, and sidecar writes. The sweep would otherwise
spend a timeout per image across the whole library while the progress bar
implied something was happening. Deferring sidecars is a real gap rather than
a hidden one — a rating made offline reaches its sidecar only when that image
is judged again while connected — and it is recorded as such at the call site.

# The "On this device" filter

A chip beside the rating filters, narrowing the grid to images whose original
is held locally. It composes with the rating terms rather than replacing them,
so "five-star frames I can actually edit on this train" is one filter. The
predicate is SQL, like the rating terms and for the same reason: the count in
the header has to agree with the cells drawn.

It reads `image_cache.tier_actual`, which nothing writes yet — the next
commit fills it. Until then the chip honestly reports zero.

`Tier` gains an explicit on-disk encoding. The variants are ordered by
generosity and the derived `Ord` invites reordering them, which would
silently reinterpret every cached row; the round-trip test is what holds the
two in agreement.

The marker was drawn from a bucket index while a click reported a
fraction of the track. Those are different quantities: bars each occupy
one equal slot whatever span of time they cover, and the index snapped
to the containing bucket's start edge, so the marker landed at the top
of whichever slot held the instant — close enough to pass on a dense
uniform axis, plainly wrong on a sparse one, and never under the click.

Send the fraction instead, computed as the exact inverse of the
interpolation the scrub handler applies, and position the marker from
it. Marker and click are now the same quantity by construction.

Scrolling the grid also left the marker behind: only an explicit scrub
ever wrote the position, so the axis claimed to say "when you are" and
stopped being true the moment the wheel moved. Map the first visible row
back to a capture time and move the marker with it.

That runs on every scroll event rather than behind the window-reload
guard, which fires a few times per screenful and would make the marker
advance in jerks. Only the marker moves, not the bars: rebuilding those
means a GROUP BY aggregate over the library, far too much for a flick,
and they do not change as the grid scrolls anyway.

dtourolleandClaude Opus 5 d49b4b41de Add thumbnail size classes and grid zoom; fix the scrub ordinal
The grid now zooms, which needs thumbnails at two resolutions rather than
one, and exposed a scrub that landed in the wrong place.

**Two thumbnail size classes.** `ThumbSize::Grid` (256px, ~10 KB) and
`Large` (1024px, ~45 KB), with the class part of the store key so both
coexist. Storing everything large would take the reference library from
~200 MB to ~860 MB, and shards sync, so that is transfer cost on every
device rather than only disk. A store written before the class existed
migrates in place: its entries are all grid-sized, which is what the
column defaults to, so nothing already fetched is discarded.

`forget` now drops every size for an image. Reading a single row left the
other class's bytes on the shard's tally for good, sealing it early on
space nothing occupied.

**Grid zoom.** Ctrl+wheel and pinch resize cells between 90px and 420px in
geometric steps, so the gesture feels the same at either end where a fixed
pixel step would be imperceptible at 400px and violent at 90px. Crossing
256px switches to the large class, so a zoomed cell is sharp rather than
upscaled. Columns and window capacity already derived from cell size, so
the grid reflows for free.

**The scrub landed about half a library too high.** It counted only dated
images while the grid shows all of them — 10,733 dated against 19,841
rows — and ignored `shadowed_by`. Verified against the live catalog: the
old formula gave 10,887, the new one 10,732, the true grid position
10,732. The scrub's count and the grid's window must use identical
predicates and ordering; a test now fails if they diverge.

**Timeline gestures are continuous.** Scrub and pan were quantised to
whole buckets, so a slow drag did nothing until it crossed a boundary and
then jumped a month. Both work in fractions of the visible span now, and
pinch-to-zoom arrives for tablet, where there is no wheel to reach the
axis with.

The pinch accumulator was wrong on first writing: it took at most one step
per update, so an 8x spread — three doublings — yielded one zoom level.
`log2().trunc()` now extracts every whole doubling and carries the
remainder. The original test asserted the wrong number and defended it in
a comment, which is worth remembering: a test can entrench a bug as
readily as catch one.

Two breaks that only appeared on a full `cargo test --workspace`.

`slint::android` exists only when compiling for Android, so darkroom-android
failed to compile on the host even though it is a workspace member. The entry

The timeline forwarded `scrub` where the Timeline component declares

dtourolle 8ad5c86ff9 Add the library, collections, and trash views; theme from style.yaml
The UI gains the views the catalog work was building toward: a windowed
library grid with ratings and flags, the collection tree with drag-to-add,
and trash with restore. derived_sync pushes thumbnail shards and the catalog
snapshot to the server's derived folder.

Tokens now have one source of truth. build.rs reads style.yaml and generates
theme.slint into OUT_DIR, which answers every existing
`import { Theme } from "theme.slint"` unchanged, because Slint resolves
imports against the importing file's directory first and the include paths
after. Generating into OUT_DIR rather than beside the hand-written Slint is
the point: a generated file sitting in ui/ looks exactly like the files
around it that are meant to be edited, and an edit to it would survive until
the next touch of style.yaml — a bug that hides for weeks. build.rs fails
loudly if a stale ui/theme.slint exists, which would otherwise shadow the
generated one silently and make every palette change vanish with no error.

The palette moves to near-neutral dark with achromatic signalling, so the
accent means "modified" or "active" rather than "heading". Shared components
land in widgets.slint: a token that binds several values into one concept is
a component, not a row in a YAML file.

Adds an optional live-style feature that makes the tokens in-out so they can
be written at startup — a feature rather than the default because it stops
the properties being constant-folded.

serde_norway is the YAML crate: serde_yaml and serde_yml are both deprecated,
and its mappings preserve insertion order, which is what lets the generated
Slint keep the token ordering the author chose.
